vue 验证两次输入的密码是否一致的方法示例

好记性不如烂笔头。总也记不住

<el-form :model='ruleForm' :rules='rules' ref='ruleForm' label- class='demo-ruleForm'> <el-form-item label='新密码' prop='newPwd'><el-input v-model='ruleForm.newPwd' clearable size='small' type='password'></el-input> </el-form-item> <el-form-item label='确认密码' prop='confirmPwd'><el-input v-model='ruleForm.confirmPwd' clearable size='small' type='password'></el-input> </el-form-item> <el-form-item><el-button type='primary' @click='submitForm(’ruleForm’)' class='button'>确定</el-button><el-button @click='resetForm(’ruleForm’)' class='button'>重置</el-button> </el-form-item></el-form>

验证两次密码是否一致 却保证输入的密码在6-16个字符之间

关键代码如下：

data() { var validatePass = (rule, value, callback) => { if (value === ’’) {callback(new Error(’请输入密码’)); } else { if (this.ruleForm.confirmPwd !== ’’) { this.$refs.ruleForm.validateField(’confirmPwd’); } callback(); } }; var validatePass2 = (rule, value, callback) => { if (value === ’’) { callback(new Error(’请再次输入密码’)); } else if (value !== this.ruleForm.newPwd) { callback(new Error(’两次输入密码不一致!’)); } else { callback(); } }; return { changePwdDialog:false,//修改密码弹框 ruleForm: { newPwd: ’’, confirmPwd:’’ }, rules: { newPwd: [ { required: true, message: ’请输入密码’, trigger: ’blur’ }, { min: 6, max: 16, message: ’长度在 6 到 16 个字符’, trigger: ’blur’ }, { validator: validatePass, trigger: ’blur’ } ], confirmPwd:[ { required: true, message: ’请确认密码’, trigger: ’blur’ }, { min: 6, max: 16, message: ’长度在 6 到 16 个字符’, trigger: ’blur’ }, { validator: validatePass2, trigger: ’blur’, required: true } ], } } },
